Beginning its 'off the grid' lifestyle in August 2015, the Cochin International airport in Southern India has become the first of its kind to operate solely on solar power. With a 1300-acre coverage itself, the airport is held up by 46,000 solar panels that produces power suitable for 10,000 homes, or the seventh largest airport in the world alone.

This solar pledge took over six months to construct and $9.5 million in funding, with other airports in the country now interested in following suit. While is is currently fully operational, the business is now looking to expand, set to cause issues for the current power supply as upgrades will be needed. The current supply is already overloaded, meaning that this airport may need to jump back on the grid or create a second solar farm of its own.

The BBC says that the move to solar power was due to multiple expensive power bills, with Cochin International management believing that the solar route will save them money in the long run.
